(30/314) 1521448 - InfoViewer JEditorPane focus/keyhandling bugs

We need visual feedback when the editor pane has focus.like a border around the thing.

When the editor pane has focus, and we are notselecting anything, the arrow keys should be handled bythe scrollpane that is wrapped around it, not by theeditorpane itself. At the moment, arrow keys movearound an invisible cursor, which is confusing - youcan press downarrow for a while, nothing happens, andthen suddenly your down arrow works but your up arrowdoesn't. Annoying.

After mouse click on the tree view, it should changefocus to the editor pane.

If tree is focused, and we press tab, where does thefocus go? It seems to be nowhere. Keys don't respond atall.
